Instead of trying to open time zone tables during calculation of CONVERT_TZ() function
or setting of @@time_zone variable we should open and lock them with the rest of
statement's table (so we should add them to global table list) and after that use such
pre-opened tables for loading info about time zones.

The code in mysql_create_table() code assumes that if lower_case_names==2 then table alias

SQL_SELECT_LIMIT as default will be applied only for SELECT statement if there was not explicit LIMIT clause
